Catalog column descriptions.

Number Name Description
1 Source_name MALS name of the source (JHHMMSS.ss+DDMMSS.s) based on its right ascension and declination (J2000) in the continuum image from SPW_id specified in column 6.
2 Pointing_id The MALS pointing ID (JHHMMSS.ss±DDMMSS.s) based on the position (J2000) of the central source in NVSS or SUMSS.
3 Obs_date_U The date and time (UTC) of the start of UHF-band observing block(s) in the format YYYY-MM-DDThh:mm.
4 Obs_date_L The date and time (UTC) of the start of L-band observing block(s) in the format YYYY-MM-DDThh:mm.
5 Obs_band The observing band: L = L-band and U = UHF-band.
6 SPW_id This identifies the SPW corresponding to the spectrum. The possible values for extragalactic spectra in the barycentric frame are LSPW_i and USPW_i; here i goes from 0 to 14. For Galactic spectra in the LSRK frame, the possible values are LSPW_10G, LSPW_13G and LSPW_14G corresponding to H I 21-cm, OHSAT1 and OHMAIN line, respectively.
7 Maj_cbeam The major axis (arcsec) of the restoring beam of the cube.
8 Min_cbeam The minor axis (arcsec) of the restoring beam of the cube.
9 PA_cbeam The position angle (degrees) of the restoring beam of the cube.
10 Peak_pos The right ascension and declination (J2000) of the pixel corresponding to flux density peak at which the spectrum is extracted.
11 Peak_pos_l The Galactic longitude (degrees) of the Peak_pos.
12 Peak_pos_b The Galactic latitude (degrees) of the Peak_pos.
13 Distance_pointing The distance of the source (arcmin) from the pointing center.
14 Scale_factor The scale factor applied for the primary beam correction. The primary beam attenuation is corrected using the katbeam (version 0.1) model.
15 Peak_flux The peak flux density (mJy beam−1) of the source.
16 Spec_rms The spectral rms (mJy beam−1 channel−1) in the unsmoothed spectrum.
17 Vis_flag This is a boolean (True or False) indicating whether an absorption feature based on visual inspection is detected in the spectrum; Nan implies no visual inspection has been performed.
18 n_clump The number of well detached absorption features detected in the spectrum.
19 n_comp The total number of Gaussian components fit to the absorption features detected in the spectrum.
20 tau_max_val The peak optical depth of the absorption feature.
21 tau_max_+err The positive 1σ error on tau_max_val.
22 tau_max_-err The negative 1σ error on tau_max_val.
23 pos_max The position of the tau_max_val; redshift (barycentric frame) for extragalactic absorption and in km s−1 (LSRK frame) relative to the rest frequency of H I 21-cm, OHSAT1 or OHMAIN line for Galactic absorption.
24 tau_int_val The integrated optical depth (km s−1).
25 tau_int_+err The positive 1σ error on tau_int_val.
26 tau_int_-err The negative 1σ error on tau_int_val.
27 delta_v The velocity width containing 50% of the tau_int_val.
28 comp_i_amp The amplitude of the ith Gaussian component fit to the absorption line.
29 comp_i_amp_+err The positive 1σ error on Comp_i_amp.
30 comp_i_amp_-err The negative 1σ error on Comp_i_amp.
31 comp_i_pos The position of the ith Gaussian component relative to pos_max (km s−1).
32 comp_i_pos_+err The positive 1σ error on Comp_i_pos.
33 comp_i_pos_-err The negative 1σ error on Comp_i_pos.
34 comp_i_sigma The width (σ in km s−1) of the ith Gaussian component.
35 comp_i_sigma_+err The positive 1σ error on Comp_i_sigma.
36 comp_i_sigma_-err The negative 1σ error on Comp_i_sigma.
